Hi everyone,
for some of you the topic of VoIP fraud might be interesting, especially if you are in VoIP/Telecoms industry. You an check the anti-fraud project at www.voipfraud.net.
According to the feedback collected during recent GTM 2007 in Washington, many people from this global industry are still not aware of the VoIP fraud threat. From my own (or my companies) experience I can say that VoIP fraud is not something that "happens to someone else"; fortunately we have managed to discover fraud attempts early enough. However, there are many thiefs outside and they could be very dangerous (some of them managed to steal out several millions dollars and to harm dozens of companies). So, probably it makes sense to inform people at least about their existence, their names and schemes they are using.
On the mentioned web-site you can find an interesting part about fraud schemes and also the list of already identified cheaters. Such information could be (at least partly) useful even for a people who are not strictly in VoIP/Telecoms business.
